Description

Shipborne built-in DIP dynamic inclined plane water surface oil spill recovery system

Technical Field

The utility model relates to a technical field that the surface of water was decontaminated especially relates to a built-in DIP developments inclined plane surface of water oil spill recovery system of shipborne.

Background

With the recent economic development of China, the demand of China on petrochemical products and energy sources is increasing. With the continuous construction of coastal petroleum facilities and the continuous rise of petroleum reserves, the threat of marine environmental safety is continuously expanding. Among these, the most immediate and greatest threat is the inclusion of oil spill accidents. Being aware of the existence of such threats, the western world has started developing relevant equipment dedicated to oil spill emergency treatment since the middle of the last century. After decades of development, oil collecting structures including brush type, dynamic ramp type, disc type, drum type, weir type, etc. exist nowadays. The mainstream oil collecting structure used in China at present is a brush type and dynamic inclined plane type oil collecting machine.

The dynamic ramp (DIP) technology was an oil recovery technology developed in the united states in the last 60 th century. The method utilizes a conveyor belt which is inclined underwater to guide the grease on the surface of the water to move downwards along the conveyor belt. After the grease leaves the conveyor belt, the oil rises upwards depending on the difference of the specific gravity of the water and the oil, and the grease can be automatically separated out. The current application of the DIP technology is divided into external hanging and internal hanging, and the external hanging is divided into side hanging and front hanging. The built-in part is a side built-in part, a bow built-in part and a catamaran hull built-in part. The technology is a ship side built-in scheme.

DIP technology has some inherent problems:

the DIP technology relies on the specific gravity difference of oil and water to complete the separation of oil and water in an oil collecting well, and the larger the specific gravity difference of oil and water is, the faster the oil floats up, and the better the separation condition is. However, for oils with similar specific gravity and water (such as heavy crude oil, heavy diesel oil for ships, and light crude oil with low carbon content volatilized from sea surface, and water hydrated, or silt adsorbed), the oil and water are difficult to be separated rapidly in the sump, and the oil which is not separated is discharged out of the body along with the drainage flow at the tail of the DIP pipe, so that the oil-water separation process fails.

The DIP technology belongs to the advancing oil collecting technology, and the chassis and the water flow must have opposite relative speeds. In operation, if the water flow has no speed or forms turbulent flow in front of the DIP conveyor belt, the relative speed of the DIP and the water flow is close to or equal to zero, the oil collecting mechanism of the DIP is not effective, and the oil on the surface layer of the water surface cannot flow to the oil collecting well along the belt.

And 3, the working process of the DIP occurs underwater, and the movement condition of the dirty oil along with water in the case and the oil-water separation condition in the oil collecting well cannot be observed from the water surface so as to intervene the abnormal condition in time.

All the operations of the DIP are in the machine box and under water, so that the observation and the manual intervention are not easy, whether the best oil receiving effect is achieved or not can not be determined, and the manual operation and the elimination are difficult when the fault occurs.

And 5, the DIP is easy to bring floating garbage on the water surface to block the DIP inlet.

The application of the built-in DIP at the ship side has no precedent abroad, and the application of the DIP in the cabin is provided after 2010 at home. According to the scheme, the DIP oil recovery machine is directly placed at the inlet of the oil recovery cabin, no water flow channel is arranged on the left side, the right side and the lower side of the DIP in the oil recovery cabin, and water entering the oil recovery cabin is discharged by a water flow generator (a drainage propeller) arranged below the rear side of the DIP.

The existing ship side built-in DIP has the following technical problems:

1. when the water flow outside the oil receiving cabin rushes into the oil receiving cabin, the upper layer water flow is blocked and cannot flow forwards continuously because the front projection surface of the DIP, which faces the oil receiving cabin wall, is also a closed surface (the rear lower end water flow generator is an open port only). When the collected oil is heavy oil, strong turbulent flow is formed in the cabin and then gradually diffuses downwards, the water generated by the water flow generator is added into the cabin to form submerged flow, the opposite relative speeds of the water flow entering the cabin and the front surface of the DIP cannot be formed, and the floating oil on the surface cannot flow to the oil collecting well along with the surface of the water casting conveyor belt. The water entering the oil receiving cabin is finally discharged from the DIP case water flow generator; the floating oil entering the cabin is accumulated in front of the engine head, so that the floating oil behind the outer side of the ship can not enter the oil collecting cabin, and is carried away from the enclosed control area by the water flow outside the cabin after being accumulated for a certain thickness to form floating oil escape.

2. When the received oil is light oil, the turbulence generated by surface water flow at the inlet of the oil receiving cabin aggravates the emulsification of floating oil, moves in the turbulence, and is partially carried into the oil collecting well by underwater undercurrent.

3. The water flow opposite to the oil recovery machine cannot be generated, so the water flow speed opposite to the oil recovery machine cannot be measured for adjusting the speed of the conveyer belt to be synchronous with the opposite water flow speed.

4. The oil-water interface of the oil collecting well is detected to determine when to start and stop the work of the oil pump, and the water is pumped to be taken due to the unstable oil-water interface of the sea wave, so that the water content of the recovered oil is high. Meanwhile, an alarm system is lacked, and the operation inspection state cannot be stopped in time when the oil pumping is abnormal.

5. The draining pump drains water directly along the cabin direction, and a great amount of water flow directly impacts the cabin wall at the draining cabin door to form turbulent flow at the draining cabin door and increase the pressure at the outlet. The water pump is difficult to discharge water outwards, and the water flow is reduced.

In addition, an underwater photography device and a lighting lamp are arranged in the DIP oil collecting well and at the inlet of the DIP case.

The working principle of the utility model is as follows:

the operation ship carries and installs in both sides the utility model discloses the system goes to the sea area that appears the oil spilling accident. After the ship arrives at an operation place, the four cabin doors at the two sides are opened, so that water enters the oil receiving cabin, and the water entering cabin is connected with various oil containment boom devices arranged at the two sides of the ship. The ship advances or reverses the water flow, so that the water flow enters the oil collecting cabin along the guide of the oil containment boom.

After the speed of the water flow carrying the surface layer floating oil and the water surface garbage is changed by the oil enclosing equipment, the water flow enters the oil collecting cabin and impacts the wall of the oil collecting cabin, so that turbulent flow is generated at the water inlet of the oil collecting cabin. And because the water flow close to the lower part of the oil fence side can escape to the outside of the oil fence, the water flow pressure of the oil spill carried by the upper side is higher, so that the speed is accelerated. After the water flow enters the oil receiving cabin, the water flow speed close to the inner side of the cabin is high, and the turbulence is more serious. Under the action of turbulent flow, the light floating oil is emulsified. The water flow passes through the waste grille 4, and larger waste which is easy to block the guide plate is blocked by the grille 4. Due to the inclination of the grid 4, waste of different depths accumulates towards the surface. When the garbage is accumulated to a certain degree, the garbage grating 4 triggers the proximity sensor 5, and the system gives an alarm. At this time, the work can be recovered by cleaning the garbage. The explosion-proof camera 2 in front of the garbage grating 4 monitors the garbage condition in real time and can be used for manually judging whether garbage blockage occurs. An air pump below the garbage grating 4 inflates air to the upward water flow through the porous sintered material plate 3, so that the upward floating of garbage is promoted, and the upward floating of emulsified light oil particles to the surface layer is accelerated.

The water flow filtered to remove the large garbage passes through the guide plate 6, and the guide plate 6 divides the water flow into a plurality of channels. The rectifying water channel in the area with serious turbulence is longer and thinner, and is shorter and wider otherwise. The high-speed turbulent flow entering the guide plate has enough long rectification space and resistance, and the water flow area flowing out of the guide plate is promoted to form a homogeneous stable flow field from top to bottom. The wind pressure blowing device 7 above the water channel of the guide plate 6 ensures that the upper layer floating oil can smoothly pass through the guide plate 6 and has basically the same speed as the water flow. A flow rate sensor 8, located opposite the outlet of the baffle, senses the velocity of the liquid exiting the baffle and communicates the data back to the control system.

The rectified water flow flows to the DIP case, and the oil guide arm 10 on the outer side of the case inlet guides the upper layer of oil spilling to the DIP inclined plane 9. It is actively connected in the groove and floats up and down along with the liquid level. The middle part of the homogeneous flow field moves towards the inclined plane 9, and the formed pressure makes part of water flow move outwards and flow out through the flow channels at the two sides and the bottom. The middle water flow is contacted with the inclined plane 9, the inclined plane 9 rotates downwards to guide the water flow to carry the top bar spilled oil to move downwards, and the water channel on the side of the box body ensures the stability of the inclined downward flow field. The middle water flow leaves the inclined plane 9 and enters the oil collecting cabin, and the spilled oil naturally floats upwards due to the difference of the specific gravity of the oil and the water. Fine refuse that is not filtered out enters the refuse cage 14. An air pressure sensor 18 and a vacuum pump 19 arranged in the oil collecting cabin are connected with a central control system, and the liquid level is automatically controlled at a required position. The oil-water mixing sensor 16 senses the water content of the oil layer, and when the water content is lower than a set value, the screw pump 15 is started to store the oil pump value in the chamber. Based on the data given by the flow sensor 8, the control system adjusts the ramp 9 to the same speed, directing the surface oil downwards. The underwater camera 17 monitors the downward oil layer and the water-oil separation condition in real time and transmits the condition to a control room. The movable door 20 arranged at the tail part of the box body can control the size of the water outlet to control the water discharging speed, and the complete separation of oil and water is ensured. The spoiler 12 arranged on the cabin body can be erected according to the requirements of a control system, the water flow speed outside the box body is adjusted, and the stability of a flow field in front of the DIP is kept. The observation window 11 arranged outside the box body can extend into the periscope for manually observing the working condition.

After exiting the DIP tank, the water again creates turbulence due to the difference in velocity and flows toward the bulkhead at the outlet 26. The rear side of the box body is provided with a guide plate 6, and the direction of the water flow is changed to the direction of delivering from the warehouse while the water flow is integrated into laminar flow. The resistance rise caused by the turbulent flow is reduced, and the water flow can flow out of the cabin more smoothly. A water flow generator 21 is provided at the bottom of the cabin near the cabin door to produce water flow and guide the water flow to be discharged. An oil-water mixing sensor 16 is arranged on the front side of the guide plate, senses the oil content of the discharged water, is connected with a control system, and gives out an alarm when the oil content exceeds a set value.

When the system is in static oil collection, the movable door 20 at the tail part of the rear side cabin door and the chassis is closed, and the trap door 22 is opened. As shown in fig. 2, a water stop end face through which only surface water flows is formed at the end face of the tail part of the case. And opening the water flow generator, discharging water at the rear side of the oil receiving cabin outwards, and enabling the water outside the oil receiving cabin to flow into the area with the separated rear part through the front part of the oil receiving cabin to form a weir type structure. The portable oil receiving machine is placed on the oil collecting tank, and the device above the oil collecting tank of the case is used for supplying energy, namely, the function of working in a static state is realized.
